init(self, address=None, timeouts=None, transport=Transport)
(Constructor)

source code

Constructor for the Client class.

Arguments are the same as for AbstractClient.

Parameters:

timeouts - timeouts to be used on connect and read/write
transport - the underlying transport to use for the RPC calls
allow_non_master - skip checks for the master node on errors

Overrides: object.__init__

_GetAddress(self)

source code

Returns the socket address

Overrides: rpc.client.AbstractClient._GetAddress: (inherited documentation)

WaitForJobChangeOnce(self, job_id, fields, prev_job_info, prev_log_serial, timeout=WFJC_TIMEOUT)

source code

Waits for changes on a job.

Parameters:

job_id - Job ID
fields (list) - List of field names to be observed
prev_job_info (None or list) - Previously received job information
prev_log_serial (None or int/long) - Highest log serial number previously received
timeout (int/float) - Timeout in seconds (values larger than WFJC_TIMEOUT will be capped to that value)
